Specification
Typical power consumption
182 W
Typical heat dissipation
590.5 BTU/hour
The AC power system supports 200-240 V AC power. It supports 110 V dual-live-wire inputs but not
110 V AC single-phase inputs. If 110 V dual-live-wire inputs are used, the voltage must range from 180
V to 264 V.
240V HVDC power system, the input voltage range from 192 V to 288 V DC. 380V HVDC power
system, the input voltage range from 260 V to 400 V.
1.8.4.7 AC PEM
The AC PEM is used to connect the AC power supply. Each PEM provides four power inputs.
The two terminals on the right side are connected to the power supply plane on the client side,
and the two terminals on the left are connected to the power supply plane on the client side.
The AC PEM is fully configured with the entire system. The system has two PEMs.
